Definitions
- the present invention relates to a method of substantially precluding the accumulation of combustible organic vapors in a storage container.
- explosive envelope the vapor/air ratio range that will support combustion.
- the vapors will not explode if the atmosphere in the storage container is overrich, which means that there is an excess of vapors and, consequently, there is insufficient air to support combustion, i.e., the vapor/air ratio is above the upper limit of the explosive envelope.
- the vapors also will not explode if the atmosphere in the storage container is too lean which means there is not enough vapor to support combustion, i.e., the vapor/air ratio is below the lower limit of the explosive envelope.
- Petroleum tankers carry crude oil as it is extracted from the ground and such crude oil normally contains considerable quantities of volatile hydrocarbons. There is no safety problem when the storage tanks of the petroleum tankers are completely filled or "topped off” with crude oil, since it is not the oil itself that is highly combustible or explosive under these conditions but rather the hydrocarbon vapors given off therefrom.
- Flash point A measure of the flammability of combustible vapors is the "flash point" which is defined as the lowest temperature at which enough vapors are given off to form a flammable mixture of vapors and air immediately above the liquid surface.
- the flash points of various solvents differ widely. Flash points are affected by temperature, barometric pressure and molecular structure. Hydrocarbon vapors have low flash points and burn or explode at temperature as low as -40° F.
- a convenient way of eliminating the hazardous condition and environmental pollution inherent in the existing practice is to control the atmosphere inside the tank so as to ensure that the vapor/air mixture remains outside of the explosive envelope even in the presence of residual crude oil.
- a combustion preventing amount of vulcanized rubber material is placed in contact with the organic compound vapors which exist above the liquid phase of said organic compound inside a container whereupon said organic compound vapors are absorbed by said vulcanized rubber in a sufficient amount to result in an atmosphere within the container which is non-explosive.
- the organic substance absorbed by the rubber material in the container is subsequently desorbed using any convenient method.
- the swollen rubber compound may be used as fuel, or as supplementary fuel in a steam boiler.
- an effective combustion preventing amount of vulcanized rubber material is placed inside a storage container which contains a volatile organic liquid and the vapors emanating therefrom or in equilibrium therewith.
- the vulcanized rubber comprises either a non-black rubber, such as, for example, buffings of white sidewall stock, comminuted rubber bands, fragmented vulcanized gum rubber, or vulcanized rubber reinforced with carbon black, such as vulcanized black rubber buffings, tread raspings (such as airplane tread raspings), and similar vulcanized carbon black reinforced rubber particles.
- a non-black rubber such as, for example, buffings of white sidewall stock, comminuted rubber bands, fragmented vulcanized gum rubber, or vulcanized rubber reinforced with carbon black, such as vulcanized black rubber buffings, tread raspings (such as airplane tread raspings), and similar vulcanized carbon black reinforced rubber particles.
- the vulcanized rubber particles employed are made up of about 20-80% by weight of non-black stock and correspondingly about 80-20% of black stock.
- Such vulcanized rubber materials are readily available as processing scrap, particularly from the tire industry, and for purposes of the invention, it is a matter of indifference whether the stocks be based on natural rubber, or on any of the synthetic rubbers used in the tire industry, for example, SBR, butyl rubber, or polychloroprene or mixtures thereof. Conventional white sidewall stocks and tread stocks are also suitable.
- Scrap tires are preferably used in the instant invention and, as noted above, are the standard rubber tires composed of vulcanizable materials (i.e., rubbers capable of crosslinking) which are compounded and vulcanized in accordance with the standard procedures found in the prior art.
- vulcanizable materials i.e., rubbers capable of crosslinking
- the vulcanizable materials are any of the unsaturated hydrocarbon polymers exemplified by the diene polymers (which may be halogenated), such as polybutadiene, polychloroprene or polyisoprene, especially polybutadiene or polyisoprene having a high content of cis-polymer or a low content of cis-polymer; copolymer rubbers such as SBR (copolymer of styrene and butadiene), butyl rubber (copolymers based on isomonoolefins such as isobutylene and a small amount, e.g., 0.25 to 10% of a conjugated diene such as isoprene), and even natural polymers such as guayule rubber, Hevea rubber and the like.
- the diene polymers which may be halogenated
- the diene polymers which may be halogenated
- the diene polymers which may be
- depolymerized rubber may be used.
- Typical of such rubbers are emulsion polymerized diene homopolymers or copolymers including butadiene-styrene copolymer or copolymers with other copolymerizable monomers such as acrylonitrile, vinylpyridine, ethyl acrylate and the like.
- the amount of scrap rubber to be used inside the storage container is dependent upon the amount of volatile organic vapors in the storage container and should be an amount sufficient to prevent combustion, i.e., to reduce the organic material in the atmosphere to a level below the explosive envelope. Obviously, this amount will vary from case to case, however, determination of the amount is not beyond the expertise of one skilled in the art and does not involve undue experimentation to ascertain same.
- the present invention can also be used in conjunction with the storage of such solvents as acetaldehyde, carbon disulfide, diethyl ether, dimethyl ether, ethyl chloride, gasoline, isobutyraldehyde, methyl ethyl ether, petroleum ether, benzene and fuel oils and other flammable liquids.
- solvents as acetaldehyde, carbon disulfide, diethyl ether, dimethyl ether, ethyl chloride, gasoline, isobutyraldehyde, methyl ethyl ether, petroleum ether, benzene and fuel oils and other flammable liquids.
- the rate of absorption of the volatile organic vapors by the scrap rubber will depend in part upon the available surface area of the rubber, it is desirable to expose the maximum surface area of the vulcanized rubber to the organic vapor as possible.
- the size of the comminuted vulcanized scrap rubber particles ranges from that just retained on about an 8 mesh screen to that just passing through about a 100 mesh screen.
- the particles will contain progressively varying sizes and fall within the range of from about 6 mesh to about 200 mesh with few, if any, particles appreciably larger or smaller than these extremes.
- the scrap rubber may be adhered to sheets of fabric which are suspended in the tanks.
- This latter approach when used, for example, on a petroleum tanker, would also produce convection currents in the crude oil containers by oscillating as the ship moves through the water.
- the vulcanized scrap rubber which is used pursuant to the present invention can be considered to be an extremely viscous liquid and, as such, can be expected to perform as a normal liquid with regard to vapor-liquid phase relations.
- the scrap rubber which is placed inside a substantially empty crude oil tank on a ship absorbs from the ambient atmosphere the volatile hydrocarbon vapors that have been desorbed by the residue of the crude oil.
- the absorption of the vapors from volatile organic solvents in accordance with the method of the present invention insures that the vapor concentration in the air does not reach the dangerous level which could produce an explosion.
- the need to remove the non-volatile crude oil residue is conveniently eliminated. This, in turn, obviates the pollution problem and substantial investment of time and effort presently attendant on discard of residue oil dregs.
- the organic vapors which have been absorbed into the vulcanized rubber may be desorbed therefrom.
- One convenient method is to expose the rubber containing said organic material to a moving current of air. This may be simply achieved by allowing the container to be exposed to outdoor conditions which would permit desorption of the vapors to the atmosphere.
- the organic material can be desorbed under controlled conditions in a heated stream of air whereby the volatile materials are driven out of the rubber and subsequently entrained on activated charcoal or condensed in a condenser.
- the rubber particles are finely ground, they may be ignored; they will then become dispersed in the next shipment of crude oil and will depolymerize under the conditions under which the crude oil is refined.
- This example illustrates the imbibition of hydrocarbon vapor by vulcanized rubber.
- a sample of tire-vent trimmings was placed in a nylon mesh bag.
- the bag and the trimmings were weighed and found to be 126.5 grams.
- the bag containing the vulcanized rubber trimmings was placed into a closed system under ambient conditions together with 10 milliliters of benzene. About 58 hours later it was noted that the container no longer held any benzene.
- the nylon bag and its contents were observed to weigh 134.6 grams: a weight gain of 8.1 grams.
- Another 10 milliliters of liquid benzene was added to the system which was then closed off. Approximately 48 hours later the liquid in the container had substantially disappeared.
- the sample now weighed 142.5 grams a weight gain of 7.9 grams over the last increment or a total weight gain of 16.0 grams or 12.6%.
